MULTIPLE-SCREEN MIXING DEVICE.

Specification of Letters Patent.

Patented Jan. 24, 1922.

Application filed July 2, 1921. Serial No. 482,219.

T 0 all 10720712, it may concern:

Be it known that I, Gnsrav F. IV. Ron- NOW, a citizen of the United States, residing at the city of Kenosha, in the county of Kenosha and State of Wisconsin, have invented a new and useful Multiple-Screen Mixing Device, of which the following is a specification.

My invention relates to improvements in a fuel mixing device for an internal combustion engine by placing within the pipe carrying fuel to such internal combustion engine or in conjunction therewith such mixing device comprising a plurality of screens and spacer devices, alternately arranged and placed within the pipe carrying fuel to such internal combustion engine. The spacers containing apertures of the same diameters as said pipe and arranged in line therewith; and the objects of my improvement are:

F irstto provide a better gasoline mixture prior to reaching the carburetor of said motors.

Second-to give such motors increased and, a more stabilized power.

Thirdto reduce the amount of gasoline or other fluid used by said motor.

I attain these objects by arranging aplurality of screens or mesh wire with meshes or spaces of a diameter of l/M of an inch, more or less, and spacer devices alternately arranged within the pipe or other proper receptacle to be placed within the pipe or as a part thereof carrying fuel to an internal combustion engine; said spacers are 1/16 of an inch in thickness, more or less, and contain apertures of the same diameter as the said pipe and arranged in line therewith.

The mechanism is illustrated in the accompanying drawings, in which- Figure I shows a mechanically machined cross section of a container or portion of a motor manifold or pipe conducting fuel to an internal combustion engine and illustrates the arrangement of the screens.

Figure I also shows the method of assembling the multiple screen mixing device ;a spacer is left on the casting; then screens and spacers are alternated and when completed the device should be about 1-3 inches long for a manifold or pipe carrying fuel to an internal combustion engine that is one inch or 1 1/8 inches in diameter. Necessarily a manifold or pipe for conducting fuel of a larger diameter would require a larger attachment.

Figure II illustrates the arrangement of the screen or meshed wires, made of copper or brass, such screen to have a mesh of 1/16 of an inch or such meshed wires to be spaced or meshed approximately 1/16 of an inch apart, and such spaces, meshes or openings to be equivalent to or larger than the smallest passage for fuel in the carburetor used on such internal combustion engine.

Figures III and IV represent the spacer used to separate the screens made of sheet metal, brass or other suitable material that will withstand heat and hold the screens in place properly, each spacer containing an aperture of the same diameter of the pipe for conducting fuel to the engine and arranged in line therewith.

Figure V shows the end of the container with bolt holes for attachment to the manifold intake pipe or engine.

Figure V also shows cross section of last spacer which should be press fitted so that screen may be held properly in place.

Figures VI and VII represent spacers with wires wound around slots or pulled through holes in the spacers to keep them in place; assembling these in the container or section of the intake pipe will produce similar results.

Figures VIII and IX show a single screen attached to a spacer ring.

Figure X shows multiple screen mixing device bolted in place between carburetor and manifold intake ready for operation.

Figure XI shows a cross section on a manifold of a motor with the multiple screen mixing device placed inside of manifold or pipe conducting fuel to an in ernal combustion engine.

I am aware that prior to my invention other fuel mixing devices for inte :1 combustion engines have been constructed; but

I claim:

A mixing device comprising a plurality of screens and spacer devices alternately arranged and attached to be placed within a pipe carrying fuel to an internal combustion engine, the spacer containing apertures 0f the same diameter as the said pipe and arranged in line therewith.
